An ice-cream seller unwittingly gets involved with a femme-fatale, leading to murder-charges, gangsters and factory payroll robberies.

Biff Jones is a driver/salesman for the Good Humor ice-cream company. He hopes to marry his girl Margie, who works as a secretary for Stuart Nagel, an insurance investigator. Margie won't marry Biff, though, because she is the sole support of her kid brother, Johnny. Biff gets involved with Bonnie, a young woman he tries to rescue from gangsters. But Biff's attempts to help her only get him accused of murder. When the police refuse to believe his story, it's up to Biff and Johnny to prove Biff's innocence and solve the crime.—Jim Beaver <[email protected]>

Ace "Good Humor" ice cream salesman Biff Jones, while on his peddling route, is attacked by three thugs chasing a platinum blonde, Bonnie Conroy. They leave after stuffing Biff into the freezer compartment of his delivery vehicle. Biff loses his job. Bonnie shows up and asks Biff to spend the night in her living-room as protection against the gang. He agrees but awakens to find Bonnie a cold corpse. Biff thinks he has killed her but when he returns with the police the corpse has disappeared. Biff is implicated in a murder and robbery at a factory where he was seen making his rounds on the night of the crime. His girlfriend, Margie Bellew, secretary to Stuart Nagel, special investigator for the Peerless Insurance Company, warns Biff he is the prime suspect. Together, they hunt for the missing blonde in order to establish his alibi. Johnny, Margie's kid brother, and fellow-members of "The Captain Marvel Club" save Biff and Margie in a schoolhouse where they have been cornered by the gang.—Les Adams <[email protected]>
